UPGRADE: Windows 7 32 Bit to 64 Bit Home Basic

I have recently bought LENOVO Z560 with pre-installed 32-bit Windows 7 Home Basic.

I want to know:
1) How can I upgrade to 64 bit Home Basic
2) How can I know/ get the PRODUCT KEY of my pre-installed 32 bit Home Basic
3) Do I need to pay extra amount if I upgrade from 32 bit to 64 bit (as, I have heard that if I purchase, I will get 32 and 64 bit OS in a single pack only)
4) Will my existing set of drivers work fine with 64 bit Home Basic. If not, from where can I get the drivers

1) To upgrade to the 64 bit OS you need the 64 bit installation Disk DVD.
2) Your computer MUST have a COA Sticker "license" for Windows 7 somewhere attached to it if you bought it retail. With the OS preinstalled. It is rectangular about 1 inch by 2 inches. It will say the name of the Operating System for which the "Product Key", on the sticker, may be used to reinstall the OS on that computer.
3) The Product Key should work with either x86 or x64 software
4) Go to the manufacturers support page for your specific model. If they don't provide 64 bit drivers. You may be biting off more than you can chew.
5) Does your Processor have the ability to run a 64 bit OS?

Your computer is definitely a 64Bit model. It is hard to understand why the retailer would have only installed the 32 Bit software, as, for him, there would have been no extra cost. Perhaps you could go to the seller and enquire? He should have the 64Bit DVD and, if you still do not have it, the key.
If it were I, and he, the seller, claims to not have the original key, I would be very apprehensive about the sale.

Well, right now, most of computer are 64Bit model, and almsot every PC installed 32Bit system. Maybe not so many people use the 64Bit system. If I got my computer with 64Bit, I will change it to 43Bit, because most of program should run with compatible mode.

1) When I bought the laptop, it was a box piece with pre-installed 32 Bit Win 7 Home Basic. No CD/ DVD was provided alongwith it. They asked me to create a rescue disk for formatting/ re-installation purpose.
2) I have executed "Upgrade Advisor", and its report was - my laptop can be upgraded to 64 Bit
3) I know that most of the softwares run on 32 Bit. But, I have 8 GB of RAM installed. With 32 bit OS, I am able to use only 4 GB. I want to make full use of 8 GB RAM.

Now,
1) Can I use the same product key (will try finding out one as BUCK_EYE_66 has adviced) as my 32 bit OS, go to Microsoft site and upgrade to 64 Bit?

OK&#65292; I had search the answer for you with Google, generally, Key is just a number wothout the different between 32Bit and 64Bit. So, if you update yo 64Bit, this key can active your system in most stitation.
And I found most of games and programs can be installed and run well in 64Bit. And there are also some methods to use 8 GB of RAM in 32Bit system, but may result to blu screen.

Here is the bottom line. If you have a license for Windows 7. It IS a license for both versions of the Operating System (x86) & (x64). You may use it to install either version. As many times as you want, on the same computer.
However, you need both versions of the installation software DVDs. And, the software is ONLY sold with a license.
